Callers may stop the SSP core requesting the interrupt so it can't be
freed unconditionally. Also use NO_IRQ like we should.

The initial patch from Lothar, and Lennert make it into a cleaner
one, modified and tested on PXA320 by Eric Miao.
This patch moves the L2 cache operations out of proc-xsc3.S into
dedicated outer cache support code.
CACHE_XSC3L2 can be deselected so no L2 cache specific code will be
linked in, and that L2 enable bit will not be set, this applies to
the following cases:
a. _only_ PXA300/PXA310 support included and no L2 cache wanted
b. PXA320 support included, but want L2 be disabled
So the enabling of L2 depends on two things:
- CACHE_XSC3L2 is selected
- and L2 cache is present
Where the latter is only a safeguard (previous testing shows it works
OK even when this bit is turned on).
IXP series of processors with XScale3 cannot disable L2 cache for the
moment since they depend on the L2 cache for its coherent memory, so
IXP may always select CACHE_XSC3L2.
Other L2 relevant bits are always turned on (i.e. the original code
enclosed by #if L2_CACHE_ENABLED .. #endif), as they showed no side
effects. Specifically, these bits are:
- OC bits in TTBASE register (table walk outer cache attributes)
- LLR Outer Cache Attributes (OC) in Auxiliary Control Register

Some boards want to change low power state of pins on-the-fly, this
function helps to facilitate that operation instead of switching
